One of my favorite websites is io9.com, which is a site dedicated to science fiction and fantasy in literature and movies. Besides the usual news and rumors about upcoming movies, there are some good essays abut science fiction trends. Those I enjoy the most.
The only problem with io9 is that it's a Gawker Media site. That means it's occasionally NSFW (Not Safe For Work), which means it's also NSFK (Not Safe For Kids). The language is fine, but sometimes the media links can get rather raunchy. It's a good resource for information, but I might not share it with my students, especially middle school students.
I also get jealous of the profiles of published authors, because I'm still trying to get my book published. Argh!
